well, the second tree looks a bit like perinniana or maybe pulverulenta and the first looks vaguely like dalrympleana but I would definitely not swear to either of those surmises unless there were pictures on the fruit and/or flowers. FWIW, vegetative reproduction (usually involving cuttings) has generally been unsuccessful for most eucalyptus species by ordinary means--even with rooting hormones, bottom heat, mist systems and greenhouse conditions. so don't recommend that as an especially reliable means to get many new plants. sorry if this isn't too much help.
